Across
  1. 3. The major line of evolution include the shark and their allies
  2. 4. It's enclosing the spiral cord
  3. 6. Tge outer panel of teeth
  4. 10. The vertebrates producing embryos wrapped in such an amnion
  5. 13. This is vertebrate with jaws
  6. 14. This arose within the protochordates
  7. 18. They are present but pairedfins and limbs are absent
  8. 21. They flex their neck laterally to retract the head
  9. 26. nearsightedness image focused in front of the retina
  10. 27. They exerts an important force on a large mass
  11. 28. A very similar animal called Yunnanozoon
  12. 30. Is a property of matter
  13. 31. Where acting forces are unbalanced we are dealing with it.
  14. 32. Where the flow is nonchaotic
  15. 34. A series of separate bones or cartilage blocks firmly joined as a backbone that defines the major body axis
  16. 36. the anterior clustering of specialized sensory organs
  17. 37. The enclosing blood vessels
  18. 39. A water flow maybe in the same direction
  19. 40. It would be "high gear muscle" more effective in sustaining the velocity of the limb
  20. 41. A condition if it experiences increased stress, tissue tends to increase in prominence
Down
  1. 1. These study the size and its consequences
  2. 2. The anterior clustering of specialized sensory organs such as paired eyes, ears, nose and other sensory organs.
  3. 5. The enclosing the spinal cord
  4. 7. Forces pressing down on an object to compact it
  5. 8. A solid cylindrical body that often encloses the notochord
  6. 9. The meaning of shell and skin
  7. 11. Describes the effect of one body ecting on another through their respective mass and acceleration
  8. 12. A solid cylindrical body that often encloses the notochord
  9. 15. Is the rate of change in an objects position
  10. 16. It reduced and flapping of the pectoral fins provides propulsion
  11. 17. It refers to its resistance to flow of a fluid
  12. 19. It is located in posteriorly
  13. 20. is a concept of the flow of events
  14. 22. Where visual fields overlap
  15. 23. This are greatly enlarged and fused to the head to give the flattened body an overall diskshaped appearance
  16. 24. There four footed verterates
  17. 25. The bone as calcium reservoir when needed some calcium is removed from bone matrix
  18. 29. They distance from weight to fulcrum
  19. 33. Is the tendency of a body to resist a change in its state of motion
  20. 35. A measurement with only magnitude and no direction
  21. 38. Is a concept of distance
